Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

RFC: The minifier haven't been stripping dead-code, and it also can't kill unused
modules, so as a temporary solution this inlines `__DEV__`, kill dead branches
and kill dead modules. For now I'm just white-listing the dev variable, but we
could definitely do better than that, but as a temporary fix this should be
helpful.
I also intend to kill some dead variables, so we can kill unused requires,
although inline-requires can also fix it.

We've been forgiving unresolved modules errors in the past but we've realized that doing so makes the codebase a bit unstable as people don't make sure to fix these errors. From now on we'll early fail and stop the packager when any module cannot be resolved (including assets)

The source maps generated by uglify are already stringified, and therefore were
being stringified twice.

Summary: @public
Since we added packager-managed assets -- internally we still think of asset dependency as a single "module". In reality there are multiple files that represent this module. This becomes important with the `getDependencies` API which is used by Buck to inform it on what to rebuild. Since `getDependencies` deals with modules, and is more of an internal API, I've introduced a new one and would go on to deprecate this.

Summary: how did this ever work?
All build jobs must pass in the platform argument.
This also turns the "platform" argument into a required one.
I added a task to infer the platform argument from the filename here: t8306875

The profiler helper shouldn't live inside the packager itself, move
it to the packager.js file with other middlewares.

Summary:
We don't currently support platform extensions in asset modules.
This adds supports for it:
```
require('./a.png');
```
Will require 'a.ios.png' if it exists and 'a.png' if it doesn't.
Summary:
Sourcemap urls were generated as just the pathname (no options) which meant that they generated source for the wrong bundle.
Even worse, there exists a race condition when multiple request to the same bundle has different types of paltform arguments (in this case one could be 'ios' and the other is undefined). The fix will this will come later as it's more involved -- will need to refactor the dependency resolver to have a per-request state.
Summary:
There's been a case where Babel can hang indefinitely on a file parse/transform. Possibly related to https://github.com/babel/babel/issues/2211
This adds a timeout to transform jobs and throws an error informing the user of the offending file. The timeout interval defaults to 10 seconds, but can be changed via an option.
Summary:
Currently the platform selection is controlled by the blacklist. However, since we want to use the same server instance for cross-platform development, we need this to be controlled per request.
One outstanding issue, is that the DependencyGraph class wasn't designed that way and it doesn't have a per-request state. This means that with the current design race conditions is possible. If we got a request for a different platfrom while processing the previous request, we may change the outcome of the previous request.
To fix this a larger refactor is needed. I'll follow up a diff to do that.
Finally, so I don't break the universe like last time, I'll leave it up to the RN guys to update the call sites.
Summary:
The word Package is overloaded, it may mean npm package, or may mean a collection of bundles. Neither is what we mean. We mean `bundle`.
This renames it and modernize some of the Bundler code.

corrected small typo in the 500 response from the packager server
Test Plan: add throw to promise function prior to error handler, run packager, cache a bundle with bundle extension URI, open /debug/packages, see clean 500 error
Summary:
@public
We cached based on url, which wasn't unique becuase some options would be defaulted. This was obvious when starting the server via fbrnios which tries to warmup the bundle.
And then when the device woke up it will send a request (that is identical in reality) but would miss the cache.
This changes the cache key into a JSON stringification of the options.
Test Plan:
* ./runJestTests.sh
* ./fbrnios.sh run

1. Default to first class support of popular image formats
2. Add tests to make sure we support other than png
Test Plan:
1. ./runJestTests.sh
2. Add test.png and test.jpg images in the Playground app dir
3. require both images and render then in the playground app
4. they render
